Hi All,
Came across this web page of a guyed tower in Russia. One things for sure I
would never climb it.
Wife tells me it says it is just over 300mtrs (she's Russian). The heights are
of other towers in Russia, at 298mtrs Ekatenburg.

I do remember a little about the radios they used on the series. The Orange
Box duplex paramedic radio was the original Motorola adventure into the medical
telemetry function. It consisted of (all inside the orange box case) an HT220
used as an exciter, and a PA out of a micor mobile low power

Astron 35A supplies and probably other sizes are
sensitive to the SCR triggering. One of the
causes I found was due to a shift in the initial
routing from the rectifier to the
capacitors. When you put a supply back together
be sure to give as much space as possible between

Notwithstanding the range of 500 to 1000 Hz deviation for subaudible tones
stated in TIA-603C, most modern radios are capable of reliably detecting
CTCSS and CDCSS modulation when deviated as low as 100 Hz. I usually set
subaudible deviation to around 400 Hz, especially for stations used in the

Some of the paper repeaters that are not working and listed on the
repeater directory need to be taken down and reassigned as they are just
tying up space and if they are not used other than for special event then
they need to go the way of the dodo.

Have you considered using an audio delay? When properly applied, a delay
unit does a fine job of eliminating squelch crashes during the hang time.
Cheaper than the RLC-MOT, too.

The RLC-MOT circuit uses the famous Motorola MICOR squelch chip, so it
works identically to what is found in the MICOR. Motorola decided some

Motorola copied their own Micor squelch action in the MSR2000 audio
